No. 247,745 Claims priority, application Belgium, Jan. 9, 1962, 612,464 2 Claims. (Cl. 222199) This invention which relates to a vibrating exhauster or discharge device for silos, has for its object to provide an exhauster which makes it possible to insure a continuous and easily regulated exhausting of the load.

For this purpose, according to the invention, the exhauster comprises a container which extends downwardly below the lower part of the silo and which is provided with a slanting bottom as well as a vibrator which is arranged below the bottom, at the location of the outlet, said outlet being provided in the side wall at the lowest level of the bottom, in such a way that the largest vibrations are imparted directly to that part of the load which is not supported by the side wall of the silo, thus causing the collapse of the load outside of the silo and the automatic replacement of this portion of the load by that part of the load which is located above the level of the outlet.

According to an advantageous embodiment, the upper edge of the discharge container is soldered to the silo along the whole periphery thereof.

According to a preferred embodiment, the upper edge of the discharge container is hung to the lower part of the silo, for instance by means of hooks.

Other details and features of the invention will stand out from the description given below by way of non limitative example and with reference to the accompanying drawings in which:

FIG. 1 as an elevation view of a silo provided with an exhauster according to the invention, which is hung on the silo by means of hooks.

FIG. 2 shows on a larger scale, the lower part of the exhauster and shows notably the outlet, the regulating valve and the vibrator position.

FIG. 3 shows on a larger scale, one of the hanging points of the exhauster in that case where said exhauster is separate from the silo and is hung by means of hooks.

FIG. 4 shows on a larger scale, one of the supporting points of the silo in that case where the exhauster is hung by means of hooks.

FIG. 5 shows on a larger scale, one of the supporting points of the silo in that case where the exhauster is integral with the silo.

In the various figures, the same reference numerals pertain to similar elements.

The silo 1 shown in FIG. 1 is of cylindrical shape and is supported on three legs 2, only two of which are to be seen in the drawing. It must however be well understood that the silo can be of any shape as long as it allows the spout 13, so that the load 3 is only exhausted when According to the invention, the exhauster comprises a container 4 which extends downwardly below the lower part 5 of the silo 1 and is provided with a slanting bottom 6, as well as with a vibrator 7. The bottom 6 is reinforced by hearns 8, while the vibrator 7 is arranged below the bottom 6 on brackets 9 which are attached to the beams 8 and which are reinforced by a cross-tie 10. The vibrator 7 is located at the level of the outlet 11 which is provided in the side wall 12 of the container 4, at the 3,216,625 Patented Nov. 9,, 1965 "ice 2. lowest level of the bottom 6. The largest vibrations are imparted directly to that part of the load which is not retained by the side wall 12, thus causing the collapsing thereof outside of the silo 1 and the automatic replacing thereof by that part of the load which is located higher, above the upper level of the outlet 11.

Opposite the exhauster outlet 11, the bottom 6 is provided with a slanting draining spout 13, the gradient of which is smaller than the angle of repose of the material which comprises the load 3 and which has such a length that that part of the load 3 which has escaped from the outlet 11 lies some distance away from the edge 14 of the spot 13, so that the load 3 is only exhausted when the vibrator 7 operates.

The outlet 11 is provided with a closure member, door or register 15 which closes the upper part of the outlet 11 and which is so adjustable that the exhauster output may easily be adjusted by bringing door 15 to the required position.

According to a preferred embodiment of the invention, the door 15 is comprised of a metal sheet which follows the profile of the side wall 12 of the container 4 and the upright walls of which are received inside vertical grooves 16, the register or door 15 being retained at the required level by a chain 17.

In the particular embodiment shown in FIG. 5, the upper edge 18 of the container 4 is soldered to the silo along the whole periphery thereof, while said silo is supported on brackets 19 which are attached to the legs 2 through resilient pads 20, which are retained in position by bolts 21.

In another particular embodiment shown in FIGS. 1, 2, 3 and 4, the upper edge 18 of the container 4 is hung to the lower part 5 of the silo 1 through books 22 which bear on brackets 23 and which are insulated therefrom by resilient pads 24. As the side wall of the silo 1 is not subject to the vibrations, the silo 1 is supported directly by brackets 19, without interposing resilient pads 20 (FIG. 4).

By suitably adjusting the distance separating the brackets 23, by means of the nuts for attaching the hooks 22, it is easily possible to vary the gradient of the bottom 6 of the container 4, so as to vary the output of exhausted material and/or to adapt the exhauster to the material which is contained in the silo.

It must be understood that the invention is in no way limited to the above embodiments and that many changes may be brought therein without departing from the scope of the invention as defined by the appended claims.

I claim:

1. A silo apparatus comprising a substantially vertical cylindrical hopper open at the bottom, and a substantially vertical cylindrical container connected to the lower side wall of said hopper for receiving material therefrom, a substantially sloped member extending completely across the entire area of said container and fixed thereto and forming an integral bottom therefor, said container having a substantially vertical discharge opening in the lower edge thereof adjacent the lowest end of said bottom, and a discharge spout formed integral with said bottom and extending outwardly through said opening and beyond said side wall and below the lowest part of said bottom, and vibration means for imparting vertical and horizontal component forces to said spout, said vibration means being located underneath said bottom, adjacent said outlet, and depending from said bottom.
